Number Sense and Numeration in K-3
Young students need to develop an understanding of numbers, number systems, and related operations. They must also come to understand a complex system of more-and-less relationships, part-whole relationships, the role of special numbers like five and ten, and connections between numbers and real-world quantities.
Know What Your Students Need to Learn
Grasping the concept of number is often difficult and does not come naturally to most students. It is important for students not only to master standard computational procedures, but also to develop number sense.
Your students need to learn to:
- determine which numbers are larger or smaller than others
- conduct quick and accurate estimates in computation and measurement
- detect arithmetic errors
- recognize place value and the effects of arithmetic operations
- understand the role of numbers and how they interrelate
- appreciate the need for numbers other than whole numbers
